Modelling of mechanical and electrical systems has become an important part of the design process. With the recent implementation of the National Energy Code of Canada for Buildings, non-prescriptive path projects now must be modelled. Our experience in modelling is available to assist with your project. We have successfully applied the IES suite of software to numerous projects large and small, and can also draw on other modelling suites such as eQuest, HAP, and CAN-Quest. We are equally comfortable working in both the ASHRAE 90.1 or NECB schemes.
